Frequently asked questions

Can the accountant prepare the CT600 if my accounts aren't done?

The CT600 needs finalised accounts - order Year-End Accounts with it and both are priced together in one request.

Do accountants handle R&D claims?

Eligibility is reviewed as part of the computation; a full R&D claim is quoted separately in the thread if needed.

Who submits the return?

You do. Your accountant is assigned to your account for this job only and is not your HMRC-authorised agent, so you submit through AccLedger's HMRC corporation tax filing connection using your own Government Gateway credentials. iXBRL accounts and computation are attached automatically.
